SIDE BEARING FOR RAILWAY-CARS.

To all ytlf/1.0m it may rovi/fern:

4lie it known that. l'. JOHN J.-HVEEM a` citizen of the United States, residin at Chivago. in the county ot Cook and tate of 5 llllinois, have invented a certain new and useful Improvement in Side Bearings for liailwaylars, ot which the following is a full, clear` concise, and exact description, reference being had to theaccompanying drawings. forming; a part ot this specification.

This invention relates to improvements 1n side hearings for railway cars.

One object of the invention is to provide a simple railway side hearing more particularly adapted for use on railway cars and eomprised-of few parts easily and cheaply manufactured and assembled.

Another object of the invention 'is to provide a side hearing of the character described and which comprises a base Casting, an anti-friction roiler, and unitary means for both guiding the roller and also for preventing the roiler from becoming disengaged from the hase casting.

lu the, drawing forming a part of this specification. Figure 1 is a part side elevation, part vertical section oi' a side hearing ernlaalying;r my improvements shown in posi'- tion between a body and truck bolster of a car. Fig'.

looking;r trom the right. ot the structure shown in Fig. 1. Fig. 13 is a vertical seetional view, taken substantially on the line 3--3 ot Fig. 1. find l `ig #l is. a. horizontal detailed sectional view, tal/.en on the line Pdt ot' Fig. 1.

ln said drawing, 1() denotes a portion ot' a. bodv holster ot' a ear and ll a portion ot' a trueklmister. the improved roller side bearing, designated generally b v the referenre A. being interposed between the holsters and secured to the trui-lr bolster.

.The improved hearing A.. as shown, comprises a base Fasting 1 2 having outstandini,y flanges 115 by which it is riveted to the truck holster, a pair ot' up-standinol side walls 14m-il and one end wall l5. 'The bottom wall ot the. hase casting 12 forms` hearing` suri'aee 1li' for the anti-friction roller 17 whirh rolls hack and forth thereon. as will be anderstmd.

in order to maintain the anti-friction roller in proper position1 and guule the saine 55 in its haelt and forth movements@ have pro- 2 is an end elevational view. y

vided a. rectangular guiding frame, designated enerally by the reference B. Said frame als shovvm'comprises a pair ot side flanges 18--18 ,which are longitudinally recessed on their inner faces, as indicated at 19, to receive the ,out-turned flanges .20 of the side walls 14: of the base asting. With this arrangement, it is obvious that the frame B is slidable horizontally with respect. to the base castinghut is' prevented trom vertical movement witlrrespect thereto. Said trame B is of substantially rectangular torni and encircles the roller 17. On either side of the roller, said frame P is provided 'with upvvardly extending curved toward each other so as to correspond to the cylindrical surface of the anti-friction roller. As clearly appears from Fig. 1. said curved lingers E21 extend above a horizontal plane passing through the axis of the roller and consequently the anti-'friction roller 17 is prevented Jfrom heeoming displaced vertically from the oase casting. lt. is also evi dent. that the anti-faction roller and the frame li will move in unison as the roller moves hack and' `forth.

ln order to maintain the roller in normal position after eaeli actuation. the frame B is provided with an extension 22 from one ond thereoiA whieh passes through a spriu housing.r '.i `formed ou the adjacent end o the base rusting 12. tiaid housing )23 has mounted therewithin a eoil spring,f 24 which lits over the. reduced end 25 of Said extiension 22. said spring 'i2-i being engaged at its ends with `followers "Eli and 27. is carried by the outer end of the reduced extension l5 so that vthe outer follower 27 moves inwardly upon inward movement of the nut 2S. thus rompi-easing the s ring 24 against the follower 2li. Similary, upon movement of the extension 2Q. to theright, as viewed in lligr. 1. the follower 26 will he engaged hy the shoulder 2l) and the spring 24 eompressed against the other follower 27. Fonseqlieutly. as the. roller 17 is moved to either side of normal, the spring? '.24 will be compressed and upon release oi pressure on the roller. the spring will expand and force the trame il and the roller li' to normal position.

After the base casting is secured in posi'- tion, the trame ill is first assembled with the anti-friction roller and the frame l and roller are slid horizontally of the base casting from the left-hand end thereof, as viewed in Fig. 1, so as to engage the frame B with the flanges 20. The spring 24 and followers 26 and 27 are placed Within -the housing 23 before the reduced extension 25 is passed through the followersfas will be understood. The nut 28 is applied nally and when all the parts are thus assembled, accidental removal of the roller or any-other part of the side bearing is prevented.

I claim:

l. In a side bearing, the combination with a retaining casting, of an antifriction roller mounted within said Acasting and bodily movable with respect thereto,V of a guiding frame slidably mounted with respect to said casting, said guiding frame having portions thereof curved to correspond wlth the curvature of the bearing surface of the roller and partly overlapping the latter to thereby prevent the roller from becoming displaced, and means for automatically returning said guiding frame to normal after feaich actuation of the roller.

2. In a side bearing for railway cars and ,side walls, of a roller the like, the combination with a retaining casting having arallel side walls, of a roller adapted to rollp between said side Walls, a frame slidably mounted on said retaining casting and having curved portions overlapping the bearing surface of the roller above the axis thereof and adapted to prevent the roller from separating' from the retaining casting, and means for centering said4 frame and roller.

3; In a roller side bearing, the combination with a base casting having upstanding adapted to roll on said base casting between said walls, a guiding frame slidably mounted on said base casting and having arms extending partly over the periphery of said roller on opposite sides of its axis, and spring means for automatically centering said frame and roller after each actuation of the side bearing.

In witness that I have hereunto subscribed my name this 30th day of April, 1917.
